Intragastric balloon therapy is an endoluminal treatment of obesity that is indicated for patients with moderate obesity (body mass index, 30–35 kg/m²) who have failed to lose weight with lifestyle and medical management. Treatment duration ranges from 4 to 12 months, and percent total body weight loss ranges from 6% to 15% at the time of balloon removal. Adverse events, such as bowel obstruction or gastric perforation, are rare, and early balloon removal because of intolerance is the most common complication. Long-term data are lacking, although weight regain after balloon removal seems to be common.
